DeathMartha MORGAN, Age 30, June Qtr 1871, Vol 11b Page 126, District of Knighton, Radnorshire
(also shown on the same page was a Joseph MORGAN and Matilda MORGANS both 0 years) It is possible that Martha may have died in childbirth and that one of these babies (or both if twins) were hers - but there's no guarantee of this - you would have to order their death certs to check - details are the same as for Martha's death)
Marriage of Thomas MORGANS & Martha GOODWIN, Dec Quarter 1868, Knighton District, Vol 11b Page 332
Birth of Emma Louisa GOODWIN, June Quarter 1865, Vol 11b Page 332
It seems that Thomas MORGANS born 1831 married at least 3 times and he was still alive aged 80 in Radnorshire.
His first wife was a Sarah Nichols (or Nicholls) married Jun Qtr 1858;
2nd wife was Martha GOODWIN married Dec Qtr 1868;
3rd wife Sarah JONES married June Qtr 1886.
What makes you think he was in Tregaron, Cardiganshire? There was two Thomas Morgan/s of similar age but they were shown as being born in Cardiganshire.
DeathThere is a death of a Thomas MORGAN shown as born about 1832
died March Qtr 1914 in the Knighton District Vol 11b Page 186
Hope this is of some help (and very sorry if I've given you too much info).
